Abstract: GA?-4?-6113 PRESS HAVING OVERLOAD RESPONSIVE SLIDE SHUT HEIGHT ADJUSTING MECHANISM     Abstract of the Disclosure The reciprocating slide of a mechanically driven press has a ball and socket type interconnection with the connecting rod of the press drive mechanism.  The socket component of the interconnection provides a rotatable adjusting screw threadedly interengaged with an annular piston received in a cylinder component on the slide.  A locking nut threadedly engages the adjusting screw and is rotatable relative thereto and to the piston to lock the adjusting screw against displacement relative to the piston.  During normal press operation the locking nut is biased against a shoulder on the cylinder by hydraulic fluid under pressure in a variable volume chamber between the piston and cylinder components.  In response to an overload on the slide, a pressure responsive relief valve releases hydraulic fluid from the chamber and enables relative movement between the piston and cylinder components and thus between the slide and connecting rod.

Abstract: ABSTRACT A packaging machine for automatically packaging articles in a honeycomb structure which includes mechanisms for providing a honeycomb structure in an expanded condition in a loading station.  The articles to be packaged are directed into the loading station, dropped into the expanded honeycomb structure, and the articles and honeycomb are subsequently dropped into the container. This is automatically done on a repeated basis until the container is filled, after which the container is automatically moved out of the loading station and a new container is moved into place.

Abstract: ABSTRACT OF THE DISCLOSURE   Projectile with at least one expellable subprojectile. The projectile is provided with a nose element, which is arranged, in a predetermined position in the trajectory of the projectile, to be discarded, thereby causing a decelerating force on the projectile. The fore subprojectile is provided with a deceleration-sensing device, which is capable of initiating the expelling of the subprojectile as a consequence of sensing said decele-ration force. The subprojectiles in behind are arranged to be expelled either as a consequence of sensing deceleration forces occurring on expelling of the subprojectile immediately in front of it, or alternatively to be expelled in a conventional way with a delay relative to one another achieved through pyrotechnic delay.

Abstract: ABSTRACT OF THE DISCLOSURE An improved process is provided for the recovery of HF in increased yield from spent aluminum reduction cell linings. The spent linings are pyrohydrolyzed in a fluidized bed reactor and the generated Na-containing vapors and gases are then contacted with a relatively finely divided source of Al2O3.  Contacting is prefer-ably accomplished in the close vicinity of the fluidized bed to obtain extended reaction between the Al2O3 source and the vapors.  This extended reaction allows conversion of the Na-containing compounds, such as NaF and Na2O to HF and an Na2OxAl2O3 compound.

Abstract: ABSTRACT OF THE DISCLOSURE     An optical system adapted to be used in a guided weapon training system having an effective live range and operative for exercising a gunner.  The weapon training system includes a conventional tracking head and an instructor's console electrically connectible to a missile guidance set.  The latter is operative to generate an error signal which drives a scoring mechanism to indicate a trainee's ability to track a target.  The optical system functions to reduce the effective range optically to a dis-tance  accommodated  within a drill hall, building classroom or the like.          The optical system includes a lens assembly sightable on a miniaturized live target along a visual line of sight, the optical system being remov-ably securable to the tracking head of the weapon training system, enabling conversion of the same for use indoors.  An infrared source is used to generate an IR signal from the target, with the optical system including a corrective lens to remove parallax between the visual line of sight and the IR signal path.  In another embodiment, the IR source is a laser mounted in close proximity to the weapon's system and operable to project a symbolic target onto a target board, there being an adjustably movable  reflecting means also provided for moving the symbolic target across the target board.

Abstract: ABSTRACT OF THE DISCLOSURE           Techniques for producing semipermeable microcapsules by interfacial polymerization are disclosed.  The  material to be encapsulated and a hydrophilic monomer are emulsified within a hydrophobic continuous phase.  Polymerization is initiated by dissolving a second monomer in the continuous phase, and occurs only at the interface of the emulsion to result in the forma-tion of macroporous, poorly defined capsule membranes.  Next, the affinity of the continuous phase for the hydrophilic monomer is varied by altering the polarity of the continuous phase.  This step is accomplished by mixing a second solvent with the continuous phase.  By controlling the affinity and the concentration of the second monomer, it is possible to produce microcapsules having uniform capsule membranes and a selected upper limit of permeability.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided herein for improving the adhesion of paint to cross-linked organopolysiloxanes.  The process includes the first step of applying at least one organosilicon compound selected from the group consisting of a silane having at least one amino group which is bonded to silicon via carbon and at least one monovalent hydrocarbon radical which is bonded to silicon via oxygen and partial hydrolyzates thereof to the cross-linked organopolysiloxane.  Then  a paint is applied thereto, the paint being selected from the group consisting of lacquers, aqueous dispersions or varnishes based on nitrocellulose, polyvinyl chloride, polyvinyl ace-tate, copolymers of polyvinyl acetate and copolymers of styrene.  This process is applicable to several different types or cross-linked organo-polysiloxanes and/or paints.  Moreover, readily available organosilicon com-positions may be used.  The process finds use on wood substrates, especially on decks of ships, where they are subsequently painted.

Abstract: ABSTRACT OF THE DISCLOSURE                 A tilting roll and tilting roll assembly for the ladder means of a venetian blind and for the ladder cord or tape of a venetian blind is described.  The tilting roll is rotatable within a base about the longitudinal axis of the roll and includes a first pair of opening portions which are circumferentially spaced from one another on opposite sides of the axis of rotation of the roll.  One cord or tape of the ladder passes over the roll in a circumferential direction into engagement with one of the opening portions while the other tape or cord also passes  over the roll in the circumferential direction from the other side and engages the other opening portion.  A second pair of opening portions are provided which are axially spaced from the first pair.  By providing two pairs of opening portions, which are axially spaced from one another, the same roll can be used at each end of the blind and the lift cords of the blind can be arranged axially inwardly of the ladder means at each end.  This has the advantage that it tends to reduce the possibility of the slats moving lengthwise relative to one another, especially in the position of the blind when the lift means are not fully tensioned, e.g. in the fully lowered position.

The values of the rolling forces of the vertical rolls during the intented passes, can be calculated, by arithmetic oprerations, independently of the above mentioned measuring so as to estimate the axial displacements of the horizontal rolls and radial displacements of the vertical rolls before the rolling by consequent pass is actually performed.  On the basis of the calculated values and of the above mentioned relation.
